Research Interests
Fundamental and applied research in my group is focused on understanding igneous, sedimentary, metamorphic, and hydrothermal processes responsible for the origin and evolution of rocks and their economic mineral deposits using mineralogy, petrology, geochemistry, stable isotope geochemistry, and modeling. Part of my expertise is specifically in magmatic, hydrothermal, and metamorphosed mineral deposits of strategic rare metal (Li, Ta, Be), Fe, and base metal sulfide deposits. I use detailed mineral and whole-rock major-, trace-element and isotope geochemistry (Fe, C, O), and state-of-the-art analytical techniques (electron microprobe, SEM-EDS, LA-ICP-MS, Raman spectroscopy, synchrotron radiation (XAS/XANES), MC-ICP-MS, and age dating, among others). Petrographic analysis, clean laboratory techniques (sample dissolution, ion exchange chromatography), theoretical and numerical modeling, and statistical analysis are common tools. My field work so far takes place in North America, South America, and Australia. I have connections with industry, private and government exploration and mining companies, and other organizations in Australia, Uruguay, the U.S., Peru, and Canada, and the potential to develop new connections.
